Let's divide 81215651 by 709
We want to figure out the number of times 81215651 can be divided by 709.

Moving on to step 1:
The number 709 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 709

Let's proceed to step 2:
81 divided by 709 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 709

Going ahead to step 3:
709 can be fit into 812 1 times, resulting in a remainder of 103.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 103 after subtracting 709 from 812.
Fetch the next digit (1) from the dividend, attach it to 103 and continue: 1031 / 709

Step 4:
The number 709 fits into 1031 1 times, leaving a remainder of 322.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 709 from 1031, we get 322.
Take the next digit (5) from the dividend and append it to 322, then repeat: 3225 / 709

Moving on to step 5:
The number 709 fits into 3225 4 times, leaving a remainder of 389.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtract 2836 from 3225 to get 389.
Fetch the next digit (6) from the dividend, attach it to 389 and continue: 3896 / 709

Advancing to step 6:
If we divide 3896 by 709, we get 5 and a remainder of 351.
Write down 5 as next digit of the result. 
Result so far: 1145.0
The remainder is 351 after subtracting 3545 from 3896.
Append the next digit (5) from the dividend to 351 and continue with: 3515 / 709

Moving on to step 7:
709 goes into 3515 4 times with a remainder of 679.
Put 4 as the next digit of the answer. 
Result so far: 11454.0
Subtracting 2836 from 3515 leaves us with 679.
Grab the next digit (1) from the dividend, add it to 679, then carry on: 6791 / 709

Going ahead to step 8:
709 can be fit into 6791 9 times, resulting in a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 114549.0
Subtracting 6381 from 6791 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 9:
709 can be fit into 4100 5 times, resulting in a remainder of 555.
Record the quotient 5 as the next digit in the result. 
Result so far: 114549.5
Deduct 3545 from 4100 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Let's proceed to step 10:
709 can be fit into 5550 7 times, resulting in a remainder of 587.
The number 7 becomes the next digit in our result. 
Result so far: 114549.57
Deduct 4963 from 5550 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 11:
5870 divided by 709 is 8 with a remainder of 198.
Put 8 as the next digit of the answer. 
Result so far: 114549.578
Deduct 5672 from 5870 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 12:
If we divide 1980 by 709, we get 2 and a remainder of 562.
The next digit of our result is 2. 
Result so far: 114549.5782
The remainder is 562 after subtracting 1418 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 13:
When dividing 5620 by 709, we get 7 with a remainder of 657.
Record the quotient 7 as the next digit in the result. 
Result so far: 114549.57827
Deduct 4963 from 5620 and we're left with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Let's proceed to step 14:
6570 divided by 709 is 9 with a remainder of 189.
The next digit of our result is 9. 
Result so far: 114549.578279
Deduct 6381 from 6570 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 15:
709 goes into 1890 2 times with a remainder of 472.
Use 2 as the next digit of our solution. 
Result so far: 114549.5782792
If we take 1418 away from 1890, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 16:
If we divide 4720 by 709, we get 6 and a remainder of 466.
Write down 6 as next digit of the result. 
Result so far: 114549.57827926
If we subtract 4254 from 4720, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Our division results in 114549.57827926 with a remaining 4.66e-07.
